write tan¤=(sec^2¤-1)^1/2
then square both, sides so, that the whole equation is converted into sec
and then solve

sec @+ tan@ = 4 ,we know,sec 2 @ - tan2@ = 1 therefore sec @ -tan@ = 1/4 so ,2sec @ = 9/4 ...sec @ = 9/8 then a triangles draw with has right angle ...we have height is √17 ,codec @ = 9/√17
